**==> picture [500 x 145] intentionally omitted <==**

**----- Start of picture text -----**<br>

## **Installation** 

## **First time calibration** 

Install and wire the sensor according to the above wiring diagram. Remember to connect the white wire, the 4th wire, to (+) supply 

The very first time the sensor is powered up, the sensor will 

automatically adapt to the surroundings and calculate an optimal sensitivity by itself – no matter what kind of plastic material to be detected. 

As long as the white wire is connected to (+) supply, the sensor will be locked and be in running mode. 

|**New**|**Action**|**Description of sensor setup**|
|---|---|---|
|First time<br>calibration|New sensor|Factory settings|
||Install the sensor in the application|-|
||Connect the sensor electrical. White wire to (+) supply|-|
||Power ON|Self-Teach: Red LED blinking<br>The sensor is now in running mode|



## **Locked sensor set-up** 

No other adjustment is needed. As long as the white wire is connected to (+) supply, the set-up of the sensor is locked, and will not change during another power down/up. 

|**Locked**|**Action**|**Description of sensor setup**|
|---|---|---|
||Sensor running|Last setup|
||Power OFF|-|
||Power ON (Startup delay 600ms)|No Self-Teach. The sensor is now in running<br>mode|



## **Re-calibration of the sensor** 

If needed, a new Self-Teach can be activated by disconnecting the white wire from (+) supply, and then connect it again to (+) supply. 

You have now activated a new Self-Teach and the sensor will now re-calibrate and calculate a new sensitivity according to the application. Be sure that the application is empty – no object to detect. 

|**Self-Teach**|**Action**|**Description of sensor setup**|
|---|---|---|
|Force new Self-<br>Teach|Disconnect white wire|-|
||Connect white wire to (+) supply|Self-Teach: Red LED blinking The sensor is<br>now in running mode|
||Power OFF|-|
||Power ON (Startup delay 600 ms)|The sensor is still in running mode|

**CA, M30, M32, DC, Self-Teach** 

Every time the white wire is being disconnected from (+) supply, the Self-Teach function will be initiated and take place when connecting it again to (+) supply 

|**Self-Teach**|**Action**|**Description of sensor setup**|
|---|---|---|
|Force new Self-<br>Teach|Power OFF|-|
||Disconnect white wire|-|
||Power ON (Startup delay 600 ms)|-|
||Connect white wire to (+) supply|Self-Teach: Red LED blinking<br>The sensor is now in running mode|



## **Remote teach-in** 

It is possible to teach-in either background or object, like the CAxxCLL sensors with normal teach-in function. 

## **Teach-in Background** 

|**Teach-in**|**Action**|**Description of sensor setup**|
|---|---|---|
|Remote Teach-<br>in background|Disconnect white wire|-|
||Be sure that the application is empty<br>Connect the white wire to (-) supply > 3 sec.<br>Remove the wire during the next 3 seconds.|The red LED will flash once per second<br>Remote teach-in of background|
||Connect white wire to (+) supply|Self-Teach: Red LED blinking<br>The sensor is now in running mode|



## **Teach-in Object** 

|**Teach-in**|**Action**|**Description of sensor setup**|
|---|---|---|
|Remote Teach-<br>in object|Disconnect white wire|-|
||Be sure that the application is **with**<br>object.<br>Connect the white wire to (-) supply > 6 sec.<br>Remove the wire during the next 3 seconds.|The red LED will flash twice per second<br>Remote teach-in of object|
||Connect white wire to (+) supply|The sensor is now in running mode|



## **Teach-in Background and Object** 

|**Teach-in**|**Action**|**Description of sensor setup**|
|---|---|---|
|Remote Teach-<br>in of back-<br>ground and<br>object|Disconnect white wire|-|
||Background: Be sure that the application is empty.<br>Connect the white wire to (-) supply > 3 sec.<br>Remove the wire during the next 3 seconds.|The red LED will flash once per second<br>Remote teach-in of background|
||Object: Be sure that the application is **with**<br>object.<br>Connect the white wire to (-) supply > 6 sec.<br>Remove the wire during the next 3 seconds.|The red LED will flash twice per second<br>Remote Teach-in of object|
||Connect white wire to (+) supply|The sensor is now in running mode|



## **Toggle between normally open and normally closed** 

It is possible to toggle between normally open and normally closed by means of the teach-in function. 

|**Teach-in**|**Action**|**Description of sensor setup**|
|---|---|---|
|Normally open<br><> Normally<br>closed|Disconnect white wire|-|
||Connect the white wire to (-) supply > 9 sec.<br>Remove the wire during the next 3 seconds.|The red LED will flash three times per sec-<br>ond<br>Toggle between NO and NC|
||Connect white wire to (+) supply|The sensor is now in running mode|
